QA1 26 Series Monotube Shock Absorber - 9in Stroke - Hyperscrew - 9-3 Valving - Steel

The QA1 26 Series shock absorber features a 2-inch diameter zinc-plated steel monotube body, offering good corrosion resistance for various track conditions. This shock is a popular choice for modifieds, late models, and other racing classes, especially on rough tracks or as a traction shock for dirt cars and bumpy asphalt circuits. The hyperscrew design uses a sealed screw with an O-ring to maintain internal nitrogen gas pressure, ensuring consistent performance. Adjustments to gas pressure in hyperscrew configurations are handled by QA1 or authorized rebuilders according to sanctioning body rules.

Inside, a 46mm piston works with deflective disc valving to give you maximum control over the vehicle at all shaft speeds. This shock is designed to be rebuilt and revalved by racers, allowing for repeatable performance tuning. Each QA1 shock is dyno-tested and serialized in the USA to confirm it meets peak performance standards before it ships out.
